A rectangle has an area of 8 square centimmetres and a perimeter of 12 cm. What are the width and breath?
vlada-n [284]
Let the Length be L and the Width be W

The area is 8 cm²
LW = 8

The perimeter is 12
2(L + W) = 12
L + W = 6

Solve L and W:
LW = 8 --------------- (1)
L + W = 6------------ (2)

Equation (2):
L + W = 6
L = 6 - W -------------- Sub into (1)
(6 - W) W = 8
6W - W² = 8
W² - 6W + 8 =0 
(W -2 )(W - 4) = 0
W = 2 or 4

When W =2, L = 6 - 2 = 4
When W = 4, L = 6 - 4 = 2

Answer: The Width is 2 cm and the Length is 4 cm

Find the coordinates of the point in the first quadrant at which the tangent line to the curve (x)^3-xy+(y)^3 =0 is parallel to
Oksanka [162]
<span>Differentiate implicitly:
</span>3x^2-y-xy'+3y^2y'=0
<span>
Solve for y
</span>y'(3y^2-x)=y-3x^2&#10;\\&#10;\\y'={y-3x^2\over3y^2-x}

<span>When the tangent is parallel to the x-axis we have y'=0, so we must solve
</span>y'={y-3x^2\over3y^2-x}=0\implies y=3x^2

<span>To find the actual value of x we plug this expression for y into the original equation
</span>x^3-3x^3+27x^6=0&#10;\\&#10;\\x^3(27x^3-2)=0\implies x=\{0,{\sqrt[3]2\over3}\}

<span>Plugging this into the formula for y above gives the points
</span>(0,0)\text{ and }({\sqrt[3]2\over3},{\sqrt[3]4\over3})

<span>which is where our tangent will be parallel to the x-axis.</span>
